It depends for which elements; decoders, yes; sinks/sources; don't know.

I never spent much time with sinks/sources, I implemented a few just as
proof-of-concept.

Nope, it's not tested for that. In Nokia we tested only
encoders/decoders, and they worked fine for the main use-cases, but
nowadays we are concentrating on gst-dsp.

About trick-mode; I've no idea, but my guess it that wouldn't work.

Patches are welcome, though :)

Cheers.
